1, chemical properties, resistance to chemical corrosion and electrochemical corrosion in steel is the best, second only to the titanium alloy.
2, physical properties, heat resistance, high temperature resistance, resistance to low temperature even ultra-low temperature.
3, mechanical property, according to the different kinds of stainless steel, the mechanical properties of each are not identical, martensite stainless steel with high strength, hardness, suitable for manufacturing is corrosion resistant and require high strength, high abrasion resistance parts, such as turbine shaft, stainless steel cutlery, stainless steel bearings, austenitic stainless steel and plastic is very good, without too much intensity but the corrosion resistance is one of the best in stainless steel, suitable for the need to be very corrosion resistant and mechanical performance requirements is not high, such as chemical plants, fertilizer plants, sulfuric acid, hydrochloric acid manufacturers of equipment material, such as, of course, also can be used in various industry, such as submarine ferritic stainless steel mechanical properties, moderate intensity is not high but, oxidation resistance, suitable for all kinds of industrial furnace parts.
4, process performance: austenitic stainless steel process performance is best, because the plastic is very good, can be processed as all kinds of plates, tubes, profiles, suitable for pressure processing, martensite stainless steel with high hardness process performance.
